Shoot super-wide, 200° accent shots with the HAL 200 6mm Fisheye Lens for Sony E Mount from Entaniya. Even when you crop your image with a 16:9 aspect ratio, you'll still be left with a 180° vertical angle of view.
Instead of an iris ring that controls diaphragm blades, this lens uses a set of aperture rings which must be manually swapped with an included tool. Exposure can also be adjusted with the two included ND filters.
Note:
This lens uses a set of aperture rings, not adjustable diaphragm blades.
Angle of View
This lens boasts a super-wide 200° when using the entirety of your full-frame sensor. Many shooters select a 16:9 aspect ratio, which makes the image appear wider by cropping the top and bottom. This reduces the vertical angle of view to 180°, flattening the top and bottom edges. Horizontally, you'll still get vignetting at the rim of the 200° AoV.
Aperture Rings
The process of changing the aperture is more complicated than turning an iris ring, requiring you to remove the lens from the camera, open the rear of the lens with an included hand tool, then swap one aperture ring for another. From an engineering perspective, the complex mechanism of the diaphragm blades is drastically simplified with these aperture ring components, but that comes at the cost of the shooter's time. The time investment of swapping aperture rings yields a valuable reward; you'll achieve bokeh with perfectly rounded highlights. Two ND filters are included to limit the frequency of aperture ring swaps.
Extra-Low Dispersion Elements
Four of the 17 elements of the lens are made with extra-low dispersion glass. This preserves the image's finer details while reducing chromatic aberration and color fringing.
